There isn't too much weight to be saved in a front hub between the lightest options but a Hope Pro II is roughly 190g so some decent weight to be saved. When you come to need a new front wheel it is hard to beat an A2Z or American Classic hub on the Stans rim of your choice for value and lightness

Betd/Goldtec 15mm AM hub - 100g dead in weight and not too expensive either.
Will be mated to a DT 240s rear with Super Comp spokes to Stans rims but with brass nipples (no way am I using alloy ones again).

Should be 1600g 650b AM wheel set that is very strong and wide but light

Did you manage to convert your A2Z front hub to 15mm? What adapters did you use?

I bought mine already converted, the problem is that end caps are not fixed to the hub itself. They fall out each time I remove the axle and take the wheel out. And I do it quite often because I have a fork-mounted Thule OutRide carrier.
